TECHNICAL FIELD

The present invention relates to a electrical system wiring diagramgenerating system, which easily generates a wiring diagram of the powersystem in buildings, offices, houses, and the like, which can besuitably used, and also relates to a power supply device and a programused for the electrical system wiring diagram generating system.

BACKGROUND ART

Recently, so-called office automation has become advanced in buildings,offices, and the like. Therefore, many computer terminals are used inthere, and they can transmit/receive data to/from each other via acommunication network.

Further, computer terminals also have been spread in houses to use theInternet, besides so-called conventional house appliances such asrefrigerators and audio visual devices had already been spread.

In such situations, for example, the following problems have arisen.

Electric power consumption in each office or each house increases, dueto the increase of electric devices which consume electric power, andthat makes it happen that the permissible current value is exceeded orthat the breaker of the panel board operates.

Even if the breaker do not operate, the electric power becomes temporaryunstable; an instantaneous power failure occurs locally; and, as aresult, these states may make data in the computer terminals disappear.Particularly, in case such an instantaneous power failure or the likeoccurs to a communication relay device, such as a hub, a router, or acommunication network server of the communication network, there arisescommunication problem.

In case such communication abnormality is occurred, originally caused bythe power supply abnormality, generally, the hardware, the software andthe like, which constitute the communication network, are analyzedfirst, and then, after thoroughly analyzing these factors, the originalcause is understood to be the power supply abnormality. Especially incase of the instantaneous power failure or the like, since the abnormalstate of the power supply disappears immediately, it is very rare caseto find out the original cause is the power supply abnormality. Thus inmost cases, it is found out that the original cause of the communicationproblem is the power supply abnormality, after the communication problemhas occurred repeatedly; and it takes long time and large man-hours tofind out the origin cause and to solve the problem.

Incidentally, it is very important to understand the state of the powersystem, from the main panel board to each of the electric devices, forconstructing a power system as to operate the communication networknormally, even in the power system abnormality and in the power supplyabnormality.

However, in many cases of rental offices and houses, it is verydifficult to understand the electric power distribution flow, from themain panel board to the wall sockets.

In addition, since there are usually electric devices in use more thanthe sockets, it is ordinary to connect a tap to the wall socket, and toconnect each of the electric devices to the tap. And whenever theshortage of the sockets occurs; each person in charge of the eachsection connects taps with each other, and connects the electric devicesto the taps.

Therefore, in most cases in the offices and houses, it is almostimpossible to draw a wiring diagram of the power system, from the mainpanel board to each of the electric devices, even if it is desired.

It is an object of the present invention to provide a electrical systemwiring diagram generating system, capable of easily generating a wiringdiagram of a power system even if the connections of electric devices tothe power supply are changed in the power system, and a power supplydevice and a program used for the electrical system wiring diagramgenerating system.

On the other hand, sincethere is little possibility to change the connecting information of thepanel board or the like, which is located in the upstream side of thepower system, the registration of these power supply equipments isusually done at the installation time, with an upstream list generatingmeans. Accordingly, the electrical system wiring diagram generatingsystem generates a wiring diagram of the power system, according to theactual connection in the power system, just by being renewed theregistered connecting information of the downstream side of the socketor the panel board, even though the whole connection of the power systemis managed continuously.

As a result, it is easy to check the position, where electric powerseems to become insufficient or the like, at the time when theconnection of the electric devices is changed, or a new electric deviceis connected in the power system. Therefore, it is possible to analyzethe trouble of the power supply system, prevent trouble and maintenance,enhance the power supply equipments properly according to the connectionof the electric devices, and the like.

Further, it is easy to find out a router and the like, which is notbacked up its power by an uninterruptible power supply, and to check theoperating state of a communication network under an abnormal conditionof the power supply, for example, with a reference to a communicationnetwork wiring diagram or the like, and that enables to operate thecommunication network, with minimizing the influence from the trouble ofthe power supply system.

The electrical system wiring diagram generating system according to thepresent invention further comprises: an evaluating means, for evaluatingthe power system, based on the connection relationship between the powersupply equipments and the electric devices, which exist in the wiringdiagram of the power system.

Applying this configuration, it is easy to understood a problem of thepower system, at the time when the connection of the electric devices ischanged, or a new electric device is connected in the power system.

The electrical system wiring diagram generating system according to thepresent invention further comprises: a trouble detecting means, fordetecting trouble in the power system; and a display means, fordisplaying the wiring diagram of the power system and the position ofthe trouble having occurred.

Further, identification information is allocated to each of the sockets1, . . . , 5, to each of independent panel boards 6, 7, and to a mainpanel board 8, for distinguishing from each other. For example, a serialnumber, such as a manufacturing number, allocated to each product can beused as the identification information. In this embodiment,identification numbers 1, 2, 3, 4, 5 are allocated to the respectivesockets 1, . . . , 5, in the order from top left, and alsoidentification numbers 1, 2, 3 are allocated to the respectiveindependent panel boards 6, 7 and to the main panel board 8, in theorder from top. When each of the sockets 1, . . . , 5 or each of thepanel boards 6, . . . , 8 needs to be explained as distinguished fromeach other, in the explanation below, it will be explained with thenumber.

To the first socket 1, four computer terminals 17, 18, 19, 20, and onecommunication relay device 21 such as a hub or a router, are connectedvia an intelligent tap 16.

To the second socket 2, a copy machine 22, and a tap 23 are connected.To the tap 23, a computer terminal 24, an intelligent uninterruptiblepower supply 25, and a printer 26 are further connected. Furthermore, tothe intelligent uninterruptible power supply 25, a communication networkserver 27 is connected.

All of the computer terminals 17, . . . , 20, 24, communication networkserver 27, intelligent tap 16, and intelligent uninterruptible powersupply 25, described above, have their respective communication devices,connected to the communication relay device 21 via the communicationnetwork 10, and transmit/receive data to/from each other via thecommunication relay device 21.

To the third socket 3, a tap 28 is connected. To the tap 28, anuninterruptible power supply 29, and a different tap 30 are furtherconnected. To the uninterruptible power supply 29, a communication relaydevice 31, and a communication network server 32 are connected. To thedifferent tap 30, a printer 33, a computer terminal 34, and anintelligent uninterruptible power supply 35 are connected. To theintelligent uninterruptible power supply 35, a computer terminal 36 isconnected.

The aforesaid plural computer terminals 34, 36, and communicationnetwork server 32, connected on the downstream side of the third socket3 in a power supply direction, have their respective communicationdevices, connected to the communication relay device 31 via thecommunication network 10, and transmit/receive data to/from each other,via the communication relay device 31. Further, the two communicationrelay devices 21, 31 described above, are also connected to each othervia the communication network 10, and data can be transmitted/receivedalso between them.

It should be noted that the intelligent uninterruptible power supply 35,on the downstream side, transmits/receives data to/from the computerterminal 36. Further, the printers 26, 33 are connected to therespective communication network servers 27, 32.

As stated above, the communication network 10 is constructed, in thepower system of the first embodiment. In such a communication network10, if power supply to either the communication relay device 21 or 31 isstopped, each of the equipments, connected to the communication relaydevice 21 or 31, cannot transmit/receive data to/from other equipments.

In the power system as described above, a power system wiring diagramgenerating program is installed in the computer terminal 36, and adownstream side connection data transmitting program is installed in thecomputer terminals 24, 34. Hereinafter, the computer terminal 36, inwhich the electrical system wiring diagram generating program isinstalled, is referred to as a electrical system wiring diagramgenerating terminal, and the two computer terminals 24, 34, in which thedownstream side connection data transmitting program is installed, arereferred to as intelligent terminals.

FIG. 2 is a circuit diagram showing a configuration of the intelligenttap 16, shown in FIG. 1.

A pair of input terminals 37 such as a plug is connected to a switch 39,whose opening/closing is controlled by a one-chip microcomputer 38.Further, internal wires, connected to the other end of the switch 39,are split into plural lines, and each pair of the plural lines connectedto each pair of output terminal pairs 40, 41, . . . , 42. Furthermore, adetection member 43, for measuring an input current and the like, isarranged between the input terminal pair 37 and the switch 39, and adetection signal of the detection member 43 is inputted to the one-chipmicrocomputer 38. It should be noted that the switch 39 is closed whenpower supply is in normal, to electrically connect the input terminalpair 37 and the plural output terminal pairs 40, 41, . . . , 42, andthat the switch 39 is opened, by the opening control of the one-chipmicrocomputer 38.

In the intelligent tap 16, particularly, between each pair of the outputterminals 40, 41, . . . , 42, a capacitor 44 as a low-pass filter isconnected; on the each of the power supply lines, between each of thecapacitors 44 and each of the output terminal pair 40, 41, . . . , or42, a coil 45 is located, to superimpose a signal from the one-chipmicrocomputer 38 into the power supply line. Moreover, to the one-chipmicrocomputer 38, a communication device 46, for transmitting/receivingdata under the control thereof, is connected.

In addition, in a memory 47, built in the one-chip microcomputer 38,there are stored a power supply abnormality monitoring program 48 forcontrolling the switch 39 to open/close, a downstream side connectiondata collecting program 49, a transmitting program 50, and so on. In thememory 47, there is also stored identification information 51, such as amanufacturing number, which is uniquely allocated to the intelligent tap16.

The power supply abnormality monitoring program 48 is cyclicallyexecuted, by the one-chip microcomputer 38, to realize a power supplyabnormality monitoring means, as a trouble detecting means in theintelligent tap 16. The power supply abnormality monitoring meansdetects in the detection signal, which is detected by itself, and judgesthe abnormality of the power supply voltage, the power supply current,or the like, and controls the switch 39 to open when the judge is inabnormal.

The downstream side connection data collecting program 49, is executedby the one-chip microcomputer 38, to realize a downstream sideconnection data collecting means, in the intelligent tap 16. Thedownstream side connection data collecting means outputs a signal, toeach of the output terminal pairs 40, 41, . . . , 42 using the coil 45,and, based on a response to the signal, collects information on electricdevices, connected on the downstream side of the intelligent tap 16 inthe power supply direction, so as to generate connection data of adownstream side of the power system, between the intelligent tap 16 andthe electric devices connected thereto, using the electric deviceinformation. It should be noted that the signal, outputted to each ofthe output terminal pairs 40, 41, . . . , 42, does not reach otheroutput terminal pairs 40, 41, . . . , 42, because the signal isattenuated by the <capacitor 44. Further, if necessary, a capacitor isalso connected on the input terminal pair 37 side, between the detectionmember 43 and the switch 39, so that the signal can be also preventedfrom reaching its upstream side in the power supply direction.

The transmitting program 50 is executed, by the one-chip microcomputer38, to realize a transmitting means in the intelligent tap 16. Thetransmitting means controls the communication device 46, to transmit theconnection data of the downstream side of the power system to thecommunication network 10, together with the identification information51 stored in the memory 47. Further, when the power supply abnormalitymonitoring means detects abnormality, the transmitting means transmitsthe detection information, to the communication network 10.

When power supply abnormality occurs, such an intelligent tap 16 stopsits power supplying to the downstream side in its power supplydirection, and transmits the notification to the communication network10. Further, the intelligent tap 16 generates the connection data of thepower system on its downstream side, and transmits the connection datato the communication network 10. The intelligent tap 16, according tothe first embodiment, generates connecting information of electricdevices in the broken line 11, as the connection data of the downstreamside of the power system, and transmits the connection data to thecommunication network 10.

FIG. 3 is a circuit diagram showing a configuration of the intelligentuninterruptible power supplies 25, 35, shown in FIG. 1.

A battery 54 is connected, to internal wires, between an input terminalpair 52, such as a plug, and an output terminal pair 53. Between thebattery 54 and the terminal pairs 52, 53, switches 56, 57, whoseopening/closing is controlled by a one-chip microcomputer 55, arerespectively connected. Further, detection members 58, 59 arerespectively arranged, for measuring an input/output current, aninput/output voltage, and the like, between the input terminal pair 52and the switch 56, and between the output terminal pair 53 and theswitch 57; and the detection signals of the detection members 58, 59 areinputted to the one-chip microcomputer 55. It should be noted that theswitches 56, 57 are closed, when power supply is normal, and the inputterminal pair 52 and the output terminal pair 53 are electricallyconnected.

In the intelligent uninterruptible power supplies 25, 35, a coil 60 isarranged, for superimposing a signal from the one-chip microcomputer 55on the power supply line of the output side. Incidentally, when thereare plural output terminal pairs, it is suitable to arrange a coil and acapacitor for each of the output terminal pairs, similarly to theintelligent tap 16. Further, to the one-chip microcomputer 55, acommunication device 61 is connected, for transmitting/receiving dataunder the control thereof.

Furthermore, in a memory 62, built in the one-chip microcomputer 55,there are stored a power supply abnormality monitoring program 63, forcontrolling the switches 56, 57 to open/close, a downstream sideconnection data collecting program 64, a transmitting program 65, and soon. In the memory 62, there is also stored identification information66, such as manufacturing numbers, which is uniquely allocated to theintelligent uninterruptible power supplies 25, 35.

It should be noted that operations, based on these programs 63, 64, . .. , 65, is basically the same as the operations, based on the same namedprogram in the intelligent tap 16; and thus the explanations thereofwill be omitted. However, since the capacitor 44 is not arranged, theswitch 56 on the input terminal pair side is controlled to open, whenthe downstream side connection data collecting means outputs a signal tothe output terminal pair 53, in order to prevent the signal fromreaching its upstream side in the power supply direction.

Such intelligent uninterruptible power supplies 25, 35 switch itssupplying power to the battery supply, to the downstream side in thepower supply direction, when power supply abnormality occurs; andtransmit the notification of it to the communication network 10.Further, the intelligent uninterruptible power supplies 25, 35 generatethe connection data of the power systems on its downstream side, andtransmit the connection data to the communication network 10. Theintelligent uninterruptible power supply 25, according to the firstembodiment, generates connecting information of electric devices in thebroken line 13, as the connection data of its downstream side of thepower system; and transmits the connection data to the communicationnetwork 10. On the other hand, the intelligent uninterruptible powersupply 35 generates connecting information of electric devices in thebroken line 15, as its connection data of the downstream side of thepower system; and transmits the connection data to the communicationnetwork 10.

FIG. 4 is a circuit diagram showing a configuration of the intelligentterminals 24, 34, shown in FIG. 1.

Each of the intelligent terminals 24, 34 includes, an internal storagemedium 70, such as a so-called hard disk, for storing an identificationinformation registering program 67, a downstream side connection dataregistering program 68, a transmitting program 69, and so on; a centralprocessing unit 71 for executing the programs; a memory 72 fortentatively storing data and the like for the programs being executed;and a system bus 73 for connecting these items to each other. Further,there are connected to the system bus 73, via an I/O port 74, acommunication device 75, a display device 76, an input device 77, and soon.

The identification information registering program 67 is executed, bythe central processing unit 71, to realize an identification informationregistering means, in the intelligent terminal 24 or 34. Theidentification information registering means stores information, whichis inputted from the input device 77 while a predetermined registrationscreen is displayed on the display device 76, in the internal storagemedium 70, as identification information of a reference power supplyequipment.

It should be noted that any of the equipment could be the referencepower supply equipment, which is selected from the panel boards 6, 7, .. . , 8, sockets 1, . . . , 5, table taps 16, 23, 28, 30, anduninterruptible power supplies 25, 32, 35, which is connected between acommercial power supply and the electric devices. In this embodiment,the third socket 3 is registered as a reference power supply equipmentin the intelligent terminal 34, and the second socket 2 is registered asa reference power supply equipment in the intelligent terminal 24.

The downstream side connection data registering program 68 is executed,by the central processing unit 71, to realize a downstream sideconnection data registering means in the intelligent terminal 24 or 34.The downstream side connection data registering means storesinformation, which is inputted from the input device 77 while apredetermined registration screen is displayed on the display device 76,in the internal storage medium 70, as connection data of a power systemon the downstream side of the reference power supply equipment in thepower supply direction.

It should be noted that operations, based on the transmitting program69, is basically the same as the operations, based on the same namedprogram in the intelligent tap 16; and thus the explanations thereofwill be omitted. Further, when the intelligent terminal 24 or 34 isconnected to an uninterruptible power supply and the like, having apower supply abnormality notification function, a power supplyabnormality monitoring program may be additionally installed in theinternal storage medium 70, and the notification of the power supplyabnormality is transmitted to the communication network 10.

Each of such intelligent terminals 24, 34 generates identificationinformation of a predetermined power supply equipment, and theconnection data of the power system on the downstream side of thepredetermined power supply equipment in the power supply direction, andtransmit them to the communication network 10. The intelligent terminal24, according to the first embodiment, generates connecting informationof electric devices in the broken line 12, as the connection data of thedownstream side of the power system; and transmits the connection datato the communication network 10. On the other hand, the intelligentterminal 34 generates connecting information of electric devices in thebroken line 14, as the connection data of the downstream side of thepower system; and transmits the connection data to the communicationnetwork 10.

FIG. 5 is a circuit diagram showing a configuration of the electricalsystem wiring diagram generating terminal 36 shown in FIG. 1.

The electrical system wiring diagram generating terminal 36 includes, aninternal storage medium 83, such as a so-called hard disk, for storing adownstream side information collecting program 78, an upstream sideconnection data registering program 79, a wiring diagram generatingprogram 80, an evaluating program 81, a monitoring program 82, and soon; a central processing unit 84 for executing these programs; a memory85 for tentatively storing data and the like in executing the programs;and a system bus 86 for connecting these items to each other. Further,there are connected to the system bus 86, via an I/O port 87, acommunication device 88, a display device 89, an input device 90, and soon.

The downstream side information collecting program 78 is executed, bythe central processing unit 84, to realize a downstream side informationcollecting means, as a receiving means, in the electrical system wiringdiagram generating terminal 36. The downstream side informationcollecting means makes the intelligent tap 16, intelligentuninterruptible power supplies 25, 35, and intelligent terminals 24, 34,connected to the communication network 10, transmit there connectiondata of there downstream side of the power systems; for example, bypolling or the like.

The upstream side connection data registering program 79 is executed, bythe central processing unit 84, to realize an upstream side connectiondata registering means, in the electrical system wiring diagramgenerating terminal 36. The upstream side connection data registeringmeans stores information, which is inputted from the input device 90while a predetermined registration screen is displayed on the displaydevice 89, in the internal storage medium 83, as connection data of theupstream side. Practically, there should be registered, at leastconnecting information between the power supply equipment, which doesnot exist in any of the connection data of the aforesaid pluraldownstream side of the power systems, and other power supply equipmentsdescribed above, as connection data of an upstream side power system;and the identification information of the power supply equipment, whichis uniquely allocated to the power supply equipment.

The wiring diagram generating program 80 is executed, by the centralprocessing unit 84, to realize a wiring diagram generating means, in theelectrical system wiring diagram generating terminal 36. The wiringdiagram generating means generates a wiring diagram of the power system,just by connecting to the connection data of the upstream side of thepower system and the connection data of the plural downstream side ofthe power systems, based on the identification information, which isuniquely allocated to each of the power supply equipments.

Practically, for example, The wiring diagram generating means, at first,generates a wiring diagram of the upstream side of the power system,based on the connection data of the upstream side of the power systemand the identification information, which is uniquely allocated to eachof the power supply equipments; and plural wiring diagram of thedownstream side of the power systems, based on the connection data ofthe downstream side of the power system and the identificationinformation, which is uniquely allocated to each of the power supplyequipments. At second, the wiring diagram generating means generates thewiring diagram of the power system, to connect the wiring diagram of theupstream side of the power system and plural wiring diagram of thedownstream side of the power systems, by finding out the identificationinformation, which is included in both of the wiring diagram of theupstream side of the power system and each of the wiring diagram of thedownstream side of the power systems.

There is another practical example for generating a wiring diagram ofthe power system; in that, the connection data of the upstream side ofthe power system and the connection data of the plural downstream sideof the power systems are included in one list, and then generating awiring diagram of the power system, according to the identificationinformation, which is uniquely allocated to each of said power supplyequipments. This another practical example has the following advantagesas compared with the former practical example.

First, as shown in FIG. 1, in case each of the intelligentuninterruptible power supplies 25, 35 and equipments operated therebyare registered in each of the intelligent terminals 24, 34, there areredundantly registered connecting information between each of theintelligent uninterruptible power supplies 25, 35 and the device 27 or36 operated thereby. And in the former example, there is somepossibility left not to generate an appropriate wiring diagram of thepower system, because plural wiring diagram of the downstream side ofthe power systems are generated from each of the redundantly registeredconnecting information; while, in the latter example, by sorting thelist and checking redundantly registered information to deleting theredundant connection information, there can be generated an appropriatewiring diagram of the power system.

Secondly, in case one of connecting information of the power supplyequipment is not properly registered in both of the connecting data ofthe downstream side of the power system and the connecting data of theupstream side of the power system, in the former example, there is somepossibility left not to generate an wiring diagram of the power system,because it is unable to connect the wiring data of the downstream sideof the power system to the wiring data of the upstream side of the powersystem; while, in the latter example, there can be generated an wiringdiagram of the power system, which is clearly displayed as obviouserror, just by making it as a rule to separate these unconnected wiringdiagrams, or to connect one of unconnected wiring diagram to another atthe predetermined position; and that makes it possible to register inaddition the connecting information in order to generate an appropriatewiring diagram of the power system.

The evaluating program 81 is executed, by the central processing unit84, to realize an evaluating means, in the electrical system wiringdiagram generating terminal 36. The evaluating means evaluates the powersystem, based on the connecting relationship between the power supplyequipments and the electric devices in the wiring diagram of the powersystem. Practically, for example, the evaluating means integrates ratedpower consumptions of the electric devices; and compares the integratedpower consumptions with the rated power of the uninterruptible powersupply 25, 32, or 35, or with the interrupting power of the independentpanel board 6 or 7 or the main panel board 8; and make the displaydevice 89 display the notification of the excess of the integrated poweras a warning.

The monitoring program 82 is executed, by the central processing unit84, to realize a monitoring means, in the electrical system wiringdiagram generating terminal 36. The monitoring means make the displaydevice 89 display the wiring diagram of the power system; and make thedisplay of the device in the displayed wiring diagram flash in reverse,when the communication device 88 receives a notification of abnormalitydetection from the intelligent tap 16, the intelligent uninterruptiblepower supply 25 or 35, or the intelligent terminal 24 or 34.

Incidentally, to display the wiring diagram for monitoring, it ispreferred to display the wiring diagram, for example, in which each ofthe display objects of the devices is laid on a bitmap, in which powersupply lines are described. This makes it possible to select each of thedisplay objects of the devices, and to display various kinds of linkedinformation, such as the state of the power consumption of the selecteddevice and so on.

Such a electrical system wiring diagram generating terminal 36 generatesa wiring diagram of the power system, based on the connection data ofthe plural downstream side of the power systems and the connection dataof the upstream side of the power system; displays the wiring diagram;and makes it possible to monitor the power system. The wiring diagram ofthe power system of the first embodiment is generated as shown in FIG.6. It should be noted that each of two-dot lines in the drawingindicates each of transmitting relationships of the connection data ofthe downstream side of the power system; and that the numeral 91indicates a range to be registered as the upstream side of the powersystem. Incidentally, the range may be changed as to include other powersupply equipment and the like, and these power supply equipments may beregistered as it.

Subsequently, operation of the whole power system wiring diagramgenerating system will be explained.

As shown in FIG. 1, one-chip microcomputers 38, 55 of the intelligenttap 16 and the intelligent uninterruptible power supplies 25, 35 startmonitoring power supply, and output signals from the output terminalpairs 40, 41, . . . , 42, 53, to obtain manufacturing numbers, serialnumbers, or the like of the devices connected to the output terminalpairs 40, 41, . . . , 42, 53, if these are connected to the socket 1 andso on. Then, they generate the connection data of the downstream side ofthe power system, by putting the collected connection data up together.The connection data of the downstream side of the power system may bestructured as records, in which the numbers applied to each of theoutput terminal pairs and the identification numbers of the equipmentsconnected thereto.

The identification information registering program 67 and the downstreamside connection data registering program 68 are executed, in each of theintelligent terminals 24, 34; and in each of the internal storage medium70 of them, there are stored the reference power supply equipment (inthis embodiment, the second socket 2 or the third socket 3), and theconnection data of downstream side of the power system, related to theequipments which are connected on the downstream side of the referencepower supply equipment in the power supply system.

Further, the upstream side connection data registering program 79 isexecuted, in the electrical system wiring diagram generating terminal36; and the connection data of the upstream side of the power system isregistered in the internal storage medium 83 thereof. Incidentally, theconnection data of the upstream side of the power system may bestructured as records, including the main panel board 8 as an upstreamside device of it and the two independent panel boards 6, 7 asdownstream side devices of it.

And in the state, in which the connection data of the upstream side ofthe power system and the connection data of the plural downstream sideof the power systems have been generated in the respective devices 16,24, 25, 34, 35, 36, and in which the downstream side informationcollecting program 78 is executed in the electrical system wiringdiagram generating terminal 36; t the intelligent tap 16, theintelligent uninterruptible power supplies 25, 35, and the intelligentterminals 24, 34 transmit their own connection data of their respectivedownstream side of the power system, to the electrical system wiringdiagram generating terminal 36, via the communication network 10, inresponse to sequential call by polling.

After the electrical system wiring diagram generating terminal 36receives the connection data of the plural downstream side of the powersystems, it records the connection data in the internal storage medium83, and executes the wiring diagram generating program 80. As a result,a wiring diagram of the power system is generated, based on thepreviously-registered connecting data of the upstream side of the powersystem and the received connecting data of the plural downstream side ofthe power systems; and is recorded in the internal storage medium 83.

After the wiring diagram of the power system is generated, theevaluating program 81 is executed, the display device 89 displays theproblem of power supply, which is analyzed on the wiring diagram of thepower system. With the problem information, a user can analyze troubleof the power supply system, give preventive maintenance against trouble,properly enhance the power supply equipments according to connectingstates of the electric devices, and the like.

Further, after generating the wiring diagram of the power system, themonitoring program 82 is executed, the display device 89 displays theinformation of an equipment in trouble, which is superimposed on awiring diagram of the power system. As a result, even in case thecommunication network 10 is in abnormal because of the abnormality ofthe power supply, it is easy to understood the original cause, just byreferring to a communication network wiring diagram and so on.

As stated above, according to the first embodiment, the wiring diagramof the power system is easily generated. Moreover, even in caseconnection of the electric devices to the power supply are changed, orthat a new electric device is added, a new wiring diagram of the powersystem is easily generated, according to the change or addition.

For example, since the connecting information of each of the electricdevices to the power system can be locally registered, by the dividingunit of the socket 1, . . . , or 5 or the panel board 6 or 7, just byregistering the connecting information, as confirming, one by one at thelocation, the connecting state of each of the electric devices in thepower supply system, the registration of each of the electric devices isdone easily. On the other hand, since there is little possibility tochange the connecting information of the panel board 8 or the like,which is located in the upstream side of the power system, theregistration of these power supply equipments is usually done at theinstallation time, using the electrical system wiring diagram generatingterminal 36. Accordingly, the electrical system wiring diagramgenerating system generates a wiring diagram of the power system,according to the actual connection in the power system, just by beingrenewed the registered connecting information of the downstream side ofthe socket 1, . . . , or 5 or the panel board 6 or 7, even though thewhole connection of the power system is managed continuously.

As a result, it is easy to check the position, where electric powerseems to become insufficient or the like, at the time when theconnection of the electric devices is changed, or a new electric deviceis connected in the power system. Therefore, it is possible to analyzethe trouble of the power supply system, prevent trouble and maintenance,enhance the power supply equipments properly according to the connectionof the electric devices, and the like.

Further, it is easy to find out a router and the like, which is notbacked up its power by an uninterruptible power supply, and to check theoperating state of a communication network 10 under an abnormalcondition of the power supply, for example, with a reference to a wiringdiagram of the communication network 10 or the like, and that enables tooperate the communication network 10, with minimizing the influence fromthe trouble of the power supply system.

The embodiment described above is a preferable embodiment of the presentinvention, and various kinds of modification are possible withoutdeparting from the purpose of the present invention. For example, theinformation from the input device 77 is registered as the connectiondata of the downstream side of the power system in the intelligentterminals 24, 34 in the embodiment described above, but the connectiondata may be automatically collected from, for example, the referencepower supply device. On the contrary, the connection data of thedownstream side of the power systems is automatically collected in theintelligent tap 16 and in the intelligent uninterruptible power supplies25, 35, but input/output devices may be provided to register theconnection data.

Further, the electrical system wiring diagram generating terminal 36collects the connection data of the downstream side of the power systemusing the existing communication network 10 in the embodiment describedabove, but it may collect the connection data using the power supplylines. Furthermore, the evaluating program 81 and the monitoring program82 are executed in the electrical system wiring diagram generatingterminal 36, but they may be executed in a different terminal.
